  • Catalytic perovskites on perovskite supports and process for preparing them
    Patent number: 4151123
    Abstract: Catalytic activity of metal oxides is enhanced through application of the metal oxide to a second metal oxide having a perovskite crystal structure.
    Type: Grant
    Filed: October 15, 1976
    Date of Patent: April 24, 1979
    Assignee: E. I. Du Pont de Nemours & Company

  • Metal oxyhalide catalytic compositions
    Patent number: 4110251
    Abstract: Metal oxyhalides of the general formula ABO.sub.3-f X.sub.f having perovskite-type crystal structures in which A and B are each cations of at least one metal and a portion of the type B cations are catalytically active; X is fluoride or chloride; and f is about from 0.01 to 1.0; useful for the promotion of oxidation and reduction reactions, including those involved in the cleanup of exhaust gases of internal combustion engines.

  • Metal oxyhalide catalyzed reactions
    Patent number: 4009242
    Abstract: Oxidation and reduction reactions using metal oxyhalide catalysts of the general formula ABO.sub.3.sub.-f X.sub.f having perovskite-type crystal structures in which A and B are each cations of at least one metal and a portion of the type B cations are catalytically active; X is fluoride or chloride; and f is about from 0.01 to 2.5.
    Type: Grant
    Filed: April 8, 1975

  • Catalyst preparation
    Patent number: 4001143
    Abstract: Catalysts useful for oxidizing carbon monoxide and other volatile carbon compounds and for reducing nitrogen oxides are prepared by heating reactive alumina impregnated with ions of a platinum metal, a lanthanide metal, and at least one alkali or alkaline earth metal in amounts which promote substantially complete incorporation of the platinum metal into an aluminum-containing complex metal oxide of the empirical formula ABO.sub.3.
